The Sapajous or Capuchins, comprising the genus Cebus, are the 

 most common monkeys seen in captivity, and most familiar to the

 surface of the cerebrum. The limbs are of moderate length, the arms 

 and legs about equal, and rather slender, while the thumb is well 

 developed, with the nails of the digits in some species compressed 

 laterally. The tail is long, covered with hair to the tip, and although 

 there is no clinging bare surface on the lower side, it is prehensile, and 

 is of great assistance in various ways, though lacking the ability to 

 assume the place of another hand, as is so eminently the case of this 

 member among the species of the genus Ateleus. As a rule the Cebi 

 are of small size, with a slender waist, and the fur is inclined to a 

 woolly texture, and usually dense upon the crown of the head, and 

 short on this part, though in some species there is an elongated tuft on
